Objective:To investigate the diagnostic value of serum Aspergillus fumigatus immunoglobulin G (IgG), bronchoalveolar lavage fluid (BALF) galactomannan antigen test (GM test) and combined detection of the two methods in chronic pulmonary aspergillosis (CPA). Methods:A total of 310 patients with suspected CPA who were hospitalized in Wuhan Pulmonary Hospital from January 2020 to December 2022 were screened. BALF-GM test and serum Aspergillus fumigatus IgG were detected. According to the inclusion and exclusion criteria, 151 confirmed or clinically diagnosed CPA patients were enrolled and 60 non-CPA cases were included as controls. The underlying diseases, clinical symptoms and imaging findings of the two groups were analyzed using case-control study. Statistical comparison was performed by chi-square test. The efficacies of BALF-GM test, serum Aspergillus fumigatus IgG test, and their combined detection for CPA were analyzed by receiver operating characteristic curve. Results:There were 130 confirmed cases and 21 clinically diagnosed cases among 151 patients with CPA, including 106 males (70.2%) with age of (54.6±15.5) years. The age of 60 non-CPA patients was (53.6±17.8) years, including 42 males (70.0%). The proportions of pulmonary tuberculosis, bronchiectasis and chronic obstructive pulmonary disease, and the incidence of hemoptysis in CPA group were 79.47%(120/151), 86.09%(130/151), 26.49%(40/151) and 43.71%(66/151), respectively, which were all higher than those in non-CPA group (10.00%(6/60), 25.00%(15/60), 8.33%(5/60) and 11.67%(7/60), respectively), and the differences were statistically significant ( χ2=86.14, 74.56, 8.44 and 19.48, respectively, all P<0.05). The proportion of interstitial lung disease in non-CPA group was 28.33%(17/60), which was higher than that in CPA group (2.65%, 4/151), and the difference was statistically significant ( χ2=31.61, P<0.001). The common imaging findings of CPA patients were pulmonary cavity (70.86%, 107/151), cavity inclusions (41.72%, 63/151) and lung damage (33.77%, 51/151). The specificity and sensitivity of serum Aspergillus fumigatus IgG for CPA diagnosis were 81.7% and 68.9%, respectively, and the area under the curve (AUC) was 0.753 (95% confidence interval (95% CI) 0.681 to 0.825, P< 0.001). The specificity and sensitivity of BALF-GM test were 76.7% and 67.5%, respectively, and the AUC was 0.724 (95% CI 0.649 to 0.800, P<0.001). The specificity and sensitivity of the two methods in series combined detection were 95.0% and 44.4%, respectively, and those of the two methods in parallel detection were 60.3% and 94.5%, respectively. The AUC of the combined diagnosis of CPA by the two methods was 0.843 (95% CI 0.783 to 0.903, P<0.001). Conclusions:Serum Aspergillus fumigatus IgG combined with BALF-GM test has a good diagnostic efficacy for CPA. The detection of serum Aspergillus fumigatus IgG is non-invasive and highly specific, which is beneficial to the early diagnosis and treatment of CPA.

Objective To compare the safety and comfort of patients with or without postoperative gastric tube placement after esophageal cancer surgery, and analyze the cost and nursing time of gastric tube placement. Methods The patients with esophageal cancer undergoing minimally invasive surgery in West China Hospital of Sichuan University in 2021 were enrolled. The patients were divided into a gastric tube indwelling group and a non gastric tube indwelling group according to whether the gastric tube was indwelled after the operation. The safety and comfort indicators of the two groups were compared. Results A total of 130 patients were enrolled. There were 66 patients in the gastric tube indwelling group, including 53 males and 13 females, aged 61.80±9.05 years and 64 patients in the non gastric tube indwelling group, including 55 males and 9 females, aged 64.47±8.00 years. Six patients in the non gastric tube indwelling group needed to place gastric tube 1 to 3 days after the operation due to their condition. There was no statistical difference in the incidence of postoperative complications between the two groups (P>0.05). The subjective comfort of patients in the gastric tube indwelling group was significantly lower than that in the non gastric tube indwelling group (P<0.001), and the incidence of foreign body sensation in the throat of patients in the gastric tube indwelling group was higher than that in the non gastric tube indwelling group (P<0.001). The average nursing time in the gastric tube indwelling group was about 59.58 minutes, and the average cost of gastric tube materials and nursing was 378.24 yuan per patient. Conclusion No gastric tube used after operation for appropriate esophageal cancer patients will not increase the incidence of postoperative complications (pulmonary infection, anastomotic leakage, chylothorax), but can increase the comfort of patients, save cost and reduce nursing workload, which is safe, feasible and economical.

Objective 聽 聽 To explore the application value of failure mode and effect analysis (FMEA) in the risk management of unplanned extubation after esophageal cancer surgery. Methods 聽 聽 A total of 1 140 patients who underwent esophageal cancer surgery in our department from January 2015 to May 2017 were selected as a control group, including 948 males and 192 females with an average age of 64.45卤4.53 years. FMEA was used to analyze the risk management process of unplanned extubation. The potential risk factors in each process were found by calculating the risk priority number (RPN) value, and the improvement plan was formulated for the key process with RPN>125 points. Then 1 117 patients who underwent esophageal cancer surgery from June 2017 to December 2019 were selected as a trial group, including 972 males and 145 females with an average age of 64.60卤5.22 years, and the FMEA risk management mode was applied. Results 聽 聽 The corrective measures were taken to optimize the high-risk process, and the RPN values of 9 high-risk processes were reduced to below 125 points after using FMEA risk management mode. The rate of unplanned extubation in the trial group was lower than that in the control group (P<0.05). Conclusion 聽 聽 The application of FMEA in the risk management of unplanned extubation after esophageal cancer surgery can reduce the rate of unplanned extubation, improve the quality of nursing, and ensure the safety of patients.

Objective: This study aimed to identify the risk factors for genitourinary fistulas and delayed fistula recognition after radical hysterectomy for cervical cancer. Methods: This study was a retrospective analysis of data collected in the Major Surgical complications of Cervical Cancer in China (MSCCCC) database from 2004–2016. Data on sociodemographic characteristics, clinical characteristics, and hospital characteristics were extracted. Differences in the odds of genitourinary fistula development were investigated with multivariate logistic regression analyses, and differences in the time to recognition of genitourinary fistula were assessed by Kruskal–Wallis test. Results: In this study, 23,404 patients met the inclusion criteria. Surgery in a cancer center, a women’s and children’s hospital, a facility in a first-tier city, or southwest region, stage IIA, type C1 hysterectomy, laparoscopic surgery and ureteral injury were associated with a higher risk of ureterovaginal fistula (UVF) (p<0.050). Surgery in southwest region, bladder injury and laparoscopic surgery were associated with greater odds of vesicovaginal fistula (VVF) (p<0.050). Surgery at cancer centers and high-volume hospitals was associated with an increase in the median time to UVF recognition (p=0.016; p=0.005). International Federation of Gynecology and Obstetrics (FIGO) stage IIA1-IIB was associated with delayed recognition of VVF (p=0.040). Conclusion Intraoperative urinary tract injury and surgical approach were associated with differences in the development of UVFs and VVFs. Patients who underwent surgery in cancer centers and high-volume hospitals were more likely to experience delayed recognition of UVF. Patients with FIGO stage IIA1-IIB disease were more likely to experience delayed recognition of VVF.

Persistent infection with high-risk human papillomavirus (HR-HPV) is a well-defined etiology of cervical cancer, but not all HR-HPV infections lead to cervical cancer, indicating that many factors are involved in the regulation of HR-HPV pathogenicity. Toll-like receptors (TLRs) are a class of pattern recognition receptors that specifically recognize pathogen-associated molecular patterns (PAMPs) to provoke host innate and adaptive immunity against viruses. Relevant studies have shown that HR-HPV alters the local immune microenvironment by regulating the expression and signaling pathways of TLRs, leading to persistent infection with HR-HPV as well as cervical cancer. This review summarized and discussed the immune function and possible pathogenesis of TLRs in HPV infection-caused cervical cancer and the application of TLRs agonists in HPV vaccines.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.

Objective:To compare the long-term oncological outcomes between laparoscopic and abdominal surgery in stage Ⅰa1 （lymph-vascular space invasion-positive, LVSI +）- Ⅰb1 cervical cancer patients with different tumor sizes. Methods:Based on the Big Database of Clinical Diagnosis and Treatment of Cervical Cancer in China (1538 project database), patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer who treated by laparoscopic or abdominal surgery were included. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) between the two surgical approaches were compared under 1∶1 propensity score matching (PSM) in different tumor diameter stratification. Results:(1) A total of 4 891 patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer who underwent laparoscopy or laparotomy from January 1, 2009 to December 31, 2016 were included in the 1538 project database. Among them, 1 926 cases in the laparoscopic group and 2 965 cases in the abdominal group. There were no difference in 5-year OS and 5-year DFS between the two groups before matching. Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS ( HR=1.367, 95% CI: 1.105-1.690, P=0.004). After 1∶1 PSM matching, 1 864 patients were included in each group, and there was no difference in 5-year OS between the two groups （94.1% vs 95.4%, P=0.151）. While, the inferior 5-year DFS was observed in the laparoscopic group (89.0% vs 92.3%, P=0.004). And the laparoscopic surgery was associated with lower 5-year DFS ( HR=1.420, 95% CI: 1.109-1.818, P=0.006). (2) In stratification analysis of different tumor sizes, and there were no difference in 5-year OS and 5-year DFS between the laparoscopic group and abdominal group in tumor size ≤1 cm, >1-2 cm and >2-3 cm stratification (all P>0.05). Cox multivariate analysis showed that laparoscopic surgery were not related to 5-year OS and 5-year DFS ( P>0.05). In the stratification of tumor size >3-4 cm, there was no difference in 5-year OS between the two groups ( P>0.05). The 5-year DFS in the laparoscopic group was worse than that in the abdominal group (75.7% vs 85.8%, P=0.025). Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS ( HR=1.705, 95% CI: 1.088-2.674, P=0.020). Conclusions:For patients with stage Ⅰa1 （LVSI +）-Ⅰb1 cervical cancer, laparoscopic surgery is associated with lower 5-year DFS, and the adverse effect of laparoscopic surgery on oncology prognosis is mainly reflected in patients with tumor size >3-4 cm. For patients with tumor sizes ≤1 cm, >1-2 cm and >2-3 cm, there are no difference in oncological prognosis between the two surgical approaches.

Objective:To analyze the clinical characteristics of intestinal tuberculosis improving the diagnosis rate of intestinal tuberculosis.Methods:From January 2014 to June 2018, at Wuhan Pulmonary Hospital, the data of clinical symptoms, laboratory examination, imaging, endoscopy, surgery and pathological examination of 205 patients with intestinal tuberculosis were retrospectively analyzed. Descriptive analysis was performed for statistical analysis.Results:Among 205 patients with intestinal tuberculosis, 145 cases were male and 60 cases were female, aged 14 to 85 years old. A total of 189 cases (92.2%) were complicated with lung tuberculosis, of which 151 cases (79.9%) were positive for sputum acid fast staining. A total of 126 cases were tested for feces acid fast staining, of which 83 cases (65.9%) were positive. A total of 60 cases (29.3%) were tested for GeneXpert Mycobacterium tuberculosis/rifampicintablet (GeneXpert MTB/RIP), of which 49 cases (81.7%) were positive. A total of 44 cases of intestinal tuberculosis were diagnosed by biopsy under electronic enteroscopy, and 21 cases were pathologically diagnosed with intestinal tuberculosis after surgical resection. The 21 patients were tested for GeneXpert MTB/RIP, of which 19 cases (90.5%) were positive and 10 cases (47.6%) were positive for tuberculin test. Six patients were clinically diagnosed with intestinal tuberculosis after effective treatment of antituberculosis drugs. Conclusions:Combination of clinical symptoms and laboratory, imaging, endoscopic and pathological examination, as well as the therapeutic effect of diagnostic antituberculosis treatment could make comprehensive diagnosis of intestinal tuberculosis. The GeneXpert MTB/RIP examination is of great value in the diagnosis of intestinal tuberculosis.

Objective: To explore the clinical application value of enhanced recovery after surgery (ERAS) in the laparoscopic surgery for cholecystolithiasis comorbid with choledocholithiasis. Methods: The prospective study was conducted. The clinicopathological data of 52 patients with cholecystolithiasis comorbid with choledocholithiasis who were admitted to the Third Affiliated Hospital of Zunyi Medical University from September 2016 to September 2018 were collected. Patients were divided into 2 groups by random number table: patients in observation group received laparoscopic cholecystectomy + choledocholithotomy + choledochoscopic exploration + T-tube drainage (or primary suture of common bile duct) and perioperative management guided by the concept of enhanced recovery after surgery (ERAS), and patients in control group received traditional perioperative management. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative complications; (4) postoperative pain scores; (5) changes in hepatic function and blood routine during perioperative period. Follow-up using outpatient examination and telephone interview was performed to detect complications during the postoperative 6 months up to March 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the paired t test or repeated ANOVA. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results: Fifty-two patients were screened for eligibility, including 20 males and 32 females, aged 25-68 years, with an average age of 53 years. There were 30 patients in the observation group and 22 in the control group. (1) Surgical situations: the operation time and volume of intraoperative blood loss were (133±19)minutes and (47±21)mL in the observation group, and (136±22)minutes and (49±23)mL in the control group, respectively, showing no significant difference between the two groups (t=-0.386, -0.211, P>0.05). (2) Postoperative situations: time to out-of-bed activity, time to initial food intake, time to first anal flatus, duration of postoperative hospital stay, and hospital expenses were (18±4)hours, (19±5)hours, (28±2)hours, (4.0±1.0)days, and (1.82±0.22)×10⁴ yuan in the observation group, and (29±7)hours, (46±9)hours, (37±4)hours, (6.6±1.6)days, and (2.25±0.29)×10⁴ yuan in the control group, respectively, showing significant differences between the two groups (t=-7.054, -14.169, -9.426, -6.582, -5.809, P<0.05). (3) Postoperative complications: 1 of 30 patients in the observation group had postoperative biliary leakage, with a postoperative complication rate of 3.3%, and was cured after symptomatic support treatment. Six of 22 patients in the control group had postoperative complication, with a postoperative complication rate of 27.3%, including 2 of biliary leakage, 1 of hemorrhage, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, and they were cured after symptomatic support treatment. There was a significant difference between the two groups (χ²=4.358, P<0.05). (4) Postoperative pain scores: from postoperative 6 hours to 48 hours, the postoperative pain score changed from 2.4±0.7 to 1.9±0.9 in the observation group, and from 4.1±0.7 to 2.9±0.9 in the control group, respectively, showing a significant difference in the changing trend between the two groups (F=78.053, P<0.05). (5) Changes in hepatic function and blood routine during perioperative period: from preoperation to postoperative 3 days, levels of alamine aminotransferase (ALT), aspartate transaminase (AST), gamma-glutamyltransferase (GGT), total bilirubin (TBil), and count of white blood cells in the observation group changed from (77±20)U/L to (53±12)U/L, from (85±22)U/L to (61±17)U/L, from (166±39)U/L to (55±24)U/L, from (40±13)μmol/L to (29±12)μmol/L, from (7.0±2.0)×10⁹/L to (6.8±1.9)×10⁹/L, and changed from (79±23)U/L to (62±14)U/L, from (88±24)U/L to (64±17)U/L, from (179±34)U/L to (74±29)U/L, from (45±13)μmol/L to (35±12)μmol/L, from (7.9±2.4)×10⁹/L to (7.5±1.9)×10⁹/L in the control group, respectively. The levels of ALT, AST, GGT, TBiL, and count of WBC showed increasing at postoperative 1 day, and decreasing at postoperative 3 days. There was no significant difference in the changing trend between the two groups (F=0.058, 0.471, 3.021, 1.593, 2.172, P>0.05). Conclusion ERAS is safe and effective in the laparoscopic surgery for choledocholithiasis comorbid with cholecystolithiasis.

Objective    To explore the relation of preoperative red blood cell distribution width (RDW) with prognosis in esophageal cancer. Methods    The PubMed, EMbase, Web of Science, Cochrane Library, VIP, Wanfang, CNKI and SinoMed databases were searched to identify potential studies assessing the correlation between preoperative RDW and prognosis of esophageal cancer patients from establishment of databases to February 2019. The endpoint events included the overall survival (OS), cancer-specific survival (CSS) and disease-free survival (DFS). The Stata 12.0 software was applied for the meta-analysis and the hazard ratio (HR) and 95% confidence interval (CI) were calculated. Results    A total of 10 retrospective studies involving 4 260 esophageal cancer patients from China or Japan were included. The score of Newcastle-Ottawa scale (NOS) of the included studies was more than 6 points. The results demonstrated that elevated preoperative RDW was significantly associated with poor CSS (HR=1.50, 95% CI 1.14 to 1.99, P=0.004) and DFS (HR=1.45, 95% CI 1.14 to 1.85, P=0.002), while no significant association between preoperative RDW and OS in esophageal cancer was observed (HR=1.17, 95% CI 0.95 to 1.45, P=0.143). Subgroup analysis based on the pathology revealed that preoperative RDW had high prognostic value in esophageal squamous carcinoma (ESCC) (HR=1.37, 95% CI 1.05 to 1.77, P=0.018). Conclusion    Preoperative RDW may be an independent prognostic factor for Chinese and  Japanese esophageal cancer patients, especially for ESCC patients. However, more prospective studies with bigger sample sizes from other countries are still needed to verify our findings.
